Design and development of three stage 5:1 pressure ratio all Blisk fan for 75/110 kN thrust class engine.

Mass flow rate 85-87 kg/s

Pressure Ratio 4.8-5.0

Isentropic efficiency 83-84%


5% growth potential should be available. GTRE would like to participate in the design process. The mode of participation will be deliberated later.

Selection of material will dictate maximum rotational speed.

Time frame for the above activities up to component level aerodynamic testing, aeromechanical testing for generating performance map, structural testing relating to life and safety is approximately five years (60 months). It also includes manufacture of five sets of hardware for testing and evaluation of above tests.

The scope of work includes Design of Fan, CAD/CAE Simulations & Analysis, Prototype Development, Performance & Functional Testing and Proving of the Fan. This includes certification level tests as per MIL 5007-E .Further, it also includes transfer of production technology to GTRE which is inclusive of setting up of infrastructure, training and assistance in manufacturing of blisks.
